【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、水切シ性に優れた熱交換器に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a heat exchanger with excellent drainage properties.
カーエアコン用蒸発器は、蛇行して折シ曲げ成。 Evaporators for car air conditioners have a meandering, folded structure.

気流とともにフィン端よシ水滴が飛び出し。Shaped. It is constructed by inserting corrugated fins formed into a corrugated shape into the straight pipe portion of a flat multi-hole pipe having a plurality of refrigerant passages and tightly fixing them. When the air outside the tube is cooled by the refrigerant flowing inside the multi-hole tube via the corrugated fins,
Moisture in the air condenses on the fin surface, and water droplets are blown downstream along the fin surface. For this reason, a large amount of water droplets accumulate on the leeward side fin end of the evaporator. This obstructs the air flow, increases ventilation resistance, and eventually causes water droplets to fly out from the fin ends along with the air flow.

食の発生が生じ易いという問題を残している。This causes problems such as discomfort to the driver inside the vehicle, and as described in the above publication, a porous member such as a mesh is provided at the leeward end of the multi-hole pipe. However, in this case, condensed water often remains on the porous member, and this remaining condensed water mixes with dust in the air, causing the proliferation of bacteria and corrosion. The problem remains that it is easy.
したがって１本発明の目的は、凝縮水の水切性を牧舎し
た熱交換器室提供することである。SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a heat exchanger chamber with improved drainage of condensed water.

近傍では、風下管端方向と多穴管の長手方向下方に沿っ
た水膜流が常時形成されておシ、この水膜流に導かれ、
風下端部の水滴はスムーズに排水される。Because the surface temperature of the multi-hole tube is cooled to a temperature lower than the dew point temperature of the air by the refrigerant flowing inside the multi-hole tube, moisture in the air condenses and the surface is covered with a water film. The rear end of the multi-hole tube is coated with a hydrophilic coating, so it has better hydrophilicity than other parts, making it easier to drain water along the multi-hole tube to the bottom of the heat exchanger. It will be held in That is, near the end of the multi-hole pipe, a water film flow is always formed along the leeward pipe end direction and the longitudinal direction downward of the multi-hole pipe, and the flow is guided by this water film flow.
Water droplets at the leeward end are drained smoothly.

ができる。This not only prevents water droplets from splashing into the vehicle, but also reduces the amount of condensed water remaining. In addition, the thickness of the hydrophilic film is several microns, and since it is constantly cleaned by the falling water film, there is no accumulation of dust or bacteria as with conventional porous materials, so there are no problems such as the generation of strange odors. It can be prevented.

長手方向下方に沿った水膜流が常時形成されておシ。When air flows into the heat exchanger from the direction of the arrow, moisture in the air condenses on the surfaces of the multi-hole tubes 1 and fins 2, which are cooled to a temperature below the dew point temperature of the air by the refrigerant in the tubes. , and grow as water droplets inside the heat exchanger. The water droplets 10 are attracted to the base of the louver by the capillary action of the V-shaped notch formed at the base of the louver 2a, and are attracted to the base of the fin 2a.
The water falls sequentially downward along the joint between the water and the multi-hole pipe 1 and is drained. However, since there is a limit to this drainage speed), during operation, some of the water droplets 10 are always retained at the joint between the fin 2 and the multi-hole pipe 1, and the water droplets 10 are carried along the fin surface with the air flow. It is blown towards the leeward end of the multi-hole pipe. Since the hydrophilic coating 20a is applied to the leeward end of the multi-hole pipe,
Drainage is well carried out below the heat exchanger along the multi-hole pipes. That is, in the vicinity of the multi-hole pipe, a water film flow is always formed along the leeward end of the pipe and the longitudinally downward direction of the multi-hole pipe.

。Guided by this water film flow, water droplets at the leeward end are smoothly drained, so that water droplets can be prevented from flying out into the vehicle along with the air flow. In addition, the thickness of the hydrophilic film is as thin as a few microns, and because it is constantly cleaned by the falling water film, there is no accumulation of dust or bacteria like with conventional porous materials, so there is no risk of rotting bacteria, etc. There is no problem of odor generation.

ィン２ケ介して冷却するものである。After being brazed together in a high-temperature furnace, the refrigerant (fluid inside the pipe) inlet pipe 3 and refrigerant outlet pipe 5 are connected, and the refrigerant flowing inside the large pipe 1 causes air to flow outside the pipe through two corrugated fins. It is used for cooling.

である。@ In Figure 4, 1a is a V-shaped groove (hereinafter simply referred to as V-shaped groove) formed at the leeward arc-shaped end of the multi-hole tube. The V-shaped groove 1a is formed in the longitudinal direction of the multi-hole tube 1, and forms a vertical groove adjacent to the fins 2. The leeward end surface of the fin 2 and the leeward end surface of the multi-hole pipe 1 are at the road surface. 2a is a looper cut and raised on the fin surface, and 6 is a refrigerant passage.

寄せられる。The water droplets 10 inside the heat exchanger are attracted to the root of the looper by capillary action in the V-shaped notch formed at the root of the looper 2a, and are gradually drawn downward along the joint between the fin 2 and the multi-hole tube 1. It falls and is drained. However, there is a limit to this drainage speed, so during operation, fin 2 and multi-hole pipe 1 are
A part of the water droplet 10 is retained at the junction with the fin, and the water droplet 10 is blown toward the leeward end of the multi-hole pipe by the air flow along the fin surface.

。すなわち、多穴管端部に吹き寄せられた水滴１０は、
水膜流に伴ってＶ字溝に流れ込み、さらにＶ字溝に沿っ
て重力により熱交換器下部に流下、排水される。As shown in Figure 6, near the V-shaped groove formed at the leeward end of the multi-hole pipe 1, condensed water is attracted by the capillary action of the V-shaped groove, so water droplets do not grow and become thin. The water is in a desert shape, and a film of water is growing toward the V-shaped groove. In other words, the water droplets 10 blown onto the end of the multi-hole tube are
It flows into the V-shaped groove along with the water film flow, and further flows down to the lower part of the heat exchanger by gravity along the V-shaped groove and is drained.

ように急に風速が増し多量に水滴が吹き寄せられた場合
前においても確実に排水することができる。In this way, a water flow is formed that constantly flows to the bottom of the heat exchanger through the V-shaped groove during operation, so when switching the car air conditioner from low to high operation to increase cooling capacity, etc. Even if the wind suddenly increases in speed and a large amount of water drops are blown towards it, the water can be drained reliably.

食の発生を防止できる。According to the present invention, condensed water blown toward the end of the leeward side multi-hole pipe can be smoothly drained. Therefore, not only can water droplets be prevented from flying out into the vehicle interior with the air 'DTb, but also almost no condensed water remains, and the propagation of germs and corrosion can be prevented.
